Sakurajima online cameras have not been posting the past few months..
today.. (july 24, 2012) we see a VERY LARGE blast occur... it is a daytime eruption.. so we're not going to see too much glowing lava or lightning off of this.. however... the size of the blast shock wave, and the size of the ash plume fallout show the magnitude of this eruption.
